greetings! i'm using the development version of bioconductor with R-devel source from 3/23, rstudio 0.98.1103 running on ubuntu 14.04.

after converting a bed-bim-fam file set to vcf with the latest github pull of plink-ng (plink v1.90), i am getting this error using "readVcf("file.vcf", geno = "B36")" :

"Error: scanVcf: _DNAencode(): key 73 not in lookup table"

originally i converted file.vcf to file.bcf using "bcftools view -O b -o file.bcf file.vcf" but both ReadVcf() and scanBcfHeader() crashed the R session! scanVcfHeader() works and using "bcftools view -h" gives:
